Summary: I have the Klipsch HD Theater 300 surround system but the new house has no good place for rear speakers on stands. So I went with in-ceiling speakers. I wanted to stay with Klipsch brand and settled on the R-2650-C II for their magnetic grills, size and good sound quality. I had the Klipsch new construction brackets installed to make installation easy. Even without these brackets I believe the installation would've been quite easy.
Pros: Easy installation Good sound quality Outlet version was like new except for the Crutchfield tape MAGNETIC GRILLES!
